 <p>The Luan <b>if</b>, <b>while</b>, and <b>repeat</b> statement are the same as in Lua except that the condition expression must return a boolean value.  Any other value type will produce an error.  This helps catch errors and makes code more readable.</p>
 
+<p>Luan adds the <b>continue</b> statement which is used inside loops.</p>
+
 <p>Luan does not have a <b>goto</b> statement.</p>

 <p>
+The <b>continue</b> statement jumps to the beginning of a
+<b>while</b>, <b>repeat</b>, or <b>for</b> loop for next iteration,
+skipping the execution of statements inside the body of loop for the current iteration:

+<pre>

+<p>
 The <b>return</b> statement is used to return values
 from a function or a chunk
 (which is an anonymous function).
